FOLDING DES K Filed Oct. 3, 1929 Patented Sept. 9, 1930 PATENT OFFICE `JOZEF BULKOWSKI, OF CHICAGO, ILLINOIS FOLDING DESK Application led October 3, 1929. Serial No. 397,008.

The present inventionrelates to foldable `desks and has for its object the construction of a desk adapted for use by two persons at a time, and which may have'two table plates,

-6 Aeach hingedly connected to a central portion, andv which table plates may be selectively closed, one or both at a given time.

A still further object of the present invention isr the provision of a foldable desk of 1o the character stated which may be suitable vfor'use by school children and which would be simple in construction and which may be easily and inexpensively manufactured.

With the above general objects in view 315 and others that will appear as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claims.

In the drawing forming a part of this application, and in which like designating characters refer to corresponding parts throughout the several views,

Fig. 1 is an elevational perspective View of the desk in its open position;

Fig. 2 is an elevational view of the bottom of the table plates when the same are in an open position;

Fig. 8 is a vcross-sectional view through a table plate and a central stationary portion of the desk showing the hinge connections therebetween; and

Fig. 4 is the end view of the desk while the same is in a folded position, with table plates partly broken away.

Referring in detail to the present drawing there is shown therein a central box-like housing 10 which ordinarily remains in a raised position with respect to the table plates 11 and 12 when'the same are in an open position.. Said housing 10 may be centrally divided into two portions by means of a central plate 13 and a plurality of partition 5.0 Said housing 10 rests upon and is rigidly affixed to the base board 16. Said base board 16 may be slightly wider than the width of the housing 10, and its upper longer edges may be curved as at 17, for the purpose hereinafter described.

Each of said table plates 11 and 12 is connected to the base board 16 by means of a plurality of hinges 18. The adjacent edges of said plates 11 and 12 are lengthwise molded to conform to the curvatures 17 of the lbase board 16. The upper portion of said base-board 16 is slightly narrower than the housing 10 for affecting longitudinal grooves 19 wherein the corresponding portion 20 of the table plates 11 and 12 are adapted to enter when said plates are in an open position. Briefly, by virtue of this construction upper portions of table plates 11 and 12, at the edges thereof which are nearest to the housing 10, will be permitted to enter below said l.housing 10, by virtue of which construction,

when plates 11 and 12 are in an open position, no "outward indication will remain whereby one could be appraised of the fact that said table plates are hingedly connected to said housing 10, andin addition this construction will not permit entrance of ldust and dirt which otherwise could find its way iii-between the plates and the housing.

At each outer corner in each table plates 11 and 12 cups 21 are positioned, said cups 21 having integrally formed flanges 22, whereby said cups 21 are affixed to the underface of saidplates 11 and 12 by means of screws 23 or other like fastenings. Receivable in each of said cups 21 is leg 24, by means of which the desk is supported. Similar cups 21l are provided in the underface of base board 16. When both table plates 11 and 12 are open, the legs 24 held in cups 21 support the device. When one of said table plates is dropped down on hinges 18 to the position shown by dotted lines on Fig. 1, then legs 24 are removed from that plate and inserted into cups 21ibeneath base board 16, as is clearly shown by dotted lines on Fig. 1. When one of said table plates 11 or 12 is permitted to drop down upon its hinges 18, that'side of the desk may be brought near to the wall and the desk in that case will Vembodiment of the present invention it is the legs are removed from one of the plates limited.
